Structural Change in a Multi-Sector Model of Growth
研究了一个多部门增长模型,其中各部门全要素生产率增速不同,推导出结构变化与平衡增长共存的条件,发现消费部门劳动力会逐渐流向生产率增速最低的部门。
We study a multisector model of growth with differences in TFP growth rates across sectors and derive sufficient conditions for the coexistence of structural change, characterized by sectoral labor reallocation and balanced aggregate growth. The conditions are weak restrictions on the utility and production functions. Along the balanced growth path, labor employed in the production of consumption goods gradually moves to the sector with the lowest TFP growth rate, until in the limit it is the only sector with nontrivial employment of this kind. The employment shares of intermediate and capital goods remain constant during the reallocation process.
